Datastore for a model?

Hello, I am making a game where players build a custom vehicle out of lots of different blocks and models. I have the building part completed, however I need to be able to save the model they make in between games. I have not used datasaves much, but I know that they are used for storing values such as level or cash of a player. The only time I used them, they were starting to overload after auto saving every minute, with less than ten numbers stored in them. I was just wondering if it would be feasible to save an entire vehicle:

car1 = workspace.Model:Clone()
--then put the car as one of the values in the table (possibly with 3 or more save files)
sessionData[playerUserId] = {car1,car2,car3}

I was simply wondering if this would be possible or if it would overload the save.

Thanks
